Tim Kaine Talks About the US Economy

The Democratic vice-presidential nominee discusses the economic issues in the election. He was talking to Kai Ryssdal from our US partner programme, Marketplace. And we get reaction to Mr Kaine's thoughts from Diana Furchtgott-Roth, who is an economic advisor to Republican presidential nominee, Donald Trump. Also in the programme, artificial intelligence will either transform our society - or destroy it. That's the view of the celebrated cosmologist, Stephen Hawking. He was speaking at the launch of a new think tank called the Centre for the Future of Intelligence, at Cambridge University here in Britain. The BBC's technology correspondent, Rory Cellan-Jones, was also there.
As more and more people choose to hop between jobs, the BBC's Elizabeth Hotson asks if constantly switching is good or bad for your career. Plus we hear from Silicon Valley entrepreneur Christian Smith about a gadget he's invented to help track down things you might have lost.
